Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(2-Bromoallyl)-1-chloro-2-fluorobenzene.
4-(2-Bromoallyl)-1-chloro-2-fluorobenzene (CAS 842140-30-1) is a high-purity analytical reference standard with the molecular formula C9H7BrClF and a molecular weight of 249.51 g/mol.
Owing to fluorine/chlorine/bromine substitution, an aromatic ring system, 4-(2-Bromoallyl)-1-chloro-2-fluorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 249.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
